That to do one needs to be proficient in Java script, right?
Nope.
In fact, with some services you only need to be proficient in typing your content and choosing your layout from a prepackaged set of themes.
A webpage can be as complex or as simple as one wishes.
My suggestion for voxx, if it's not already on his to-do list, is to look at a bunch of painting company websites, save the site address and make note of the features he likes in each page. Doing this, the designer will be able to quickly get an idea and it will enable a better product from the perspective of the customer, which is voxx.
Key things should be contact info, examples of work, and any industry/local affiliations, BBB data if available, etc.
From there, nice pictures of work, before and after especially, as the before pictures will enhance the relative appearance of the after (which I'm sure is solid).
Depending, he might even want to have some video of his guys working, a spoken piece from him, etc.
He could probably get some really good work out of local community college folks, including photography, videography, and website design.
Or, he could go with a prepackaged service and just input the necessary info and photos.
